A phone company offers two monthly plans. Plan A costs $24.00 plus an additional $0.14 for each minute of calls. Plan B costs $14.00 plus an additional $0.16 for each minute of calls. For what amount of calling do the two plans cost the same?

500 minutes

Step-by-step explanation:

Equation for A: C = 0.14t+24

Equation for B: C = 0.16t+14  (t is time in minutes and C is cost)

To find the value of t where both values are the same, we make the equations equal to each other.

0.14t+24=0.16t+14

0.02t=10

t=500

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
